Definitions

  • the invention relates to an arrangement according to the preamble of claim 1 and a wind turbine according to the preamble of claim 12.
  • Arrangements are known from the prior art for resiliently fixing a housing of a gearbox of a wind turbine in a nacelle of the wind turbine.
  • the housing is supported in the nacelle via cylindrical elastomers.
  • a central axis of the elastomers is aligned parallel to a rotation axis of an input shaft of the transmission.
  • the invention is based on the object of improving the fixation of a housing of a wind power transmission in a nacelle. This object is achieved by an arrangement according to claim 1 and a wind turbine according to claim 12. Preferred developments are contained in the subclaims and result from the following description.
  • the arrangement according to the invention serves to fix a housing of a wind turbine transmission, that is to say a transmission intended for use in a wind turbine, in a nacelle of the wind turbine.
  • One wall of the housing encapsulates a cavity in which the innards of the transmission, such as shafts, bearings and gears, are located.
  • the housing can encapsulate a rotor or input shaft of the transmission and its bearings.
  • a nacelle refers to a device for holding the drive train of a wind turbine.
  • the nacelle comprises a support structure for fixing the drive train, in particular for fixing a transmission contained in the drive train.
  • the arrangement according to the invention includes a means fixed to the housing, a means fixed to the nacelle and at least two spring devices - a first spring device and a second spring device.
  • a means fixed to the housing refers to a means that is connected to the housing in a fixed manner, that is, without the possibility of relative movement.
  • a gondola-fixed means means a means that is permanently connected to the gondola.
  • a spring device is a device consisting of one or more spring elements.
  • Elastomers i.e. means made of an elastomer, or hydraulic bearings are used as spring elements.
  • the first spring device and the second spring device support the means fixed to the housing against the means fixed to the nacelle. So you connect the means fixed to the housing in a force-conducting and resilient manner to the means fixed to the nacelle.
  • the first spring device and the second spring device are preferably joined to the means fixed to the housing and/or the means fixed to the nacelle.
  • the spring devices support the means fixed to the housing in opposite directions along a support axis against the means fixed to the nacelle.
  • the first spring device therefore supports the means fixed to the housing against the means fixed to the nacelle in a first direction.
  • the second spring device supports the means fixed to the housing against the means fixed to the nacelle in a second direction.
  • the first direction and the second direction are opposite to each other. If the first spring device is loaded in compression, the second spring device is loaded in tension in the opposite direction. Conversely, if the second spring device is loaded in compression, the first spring device is loaded in tension in the opposite direction.
  • the support axis preferably runs orthogonally to an axis of rotation of an input shaft of the wind turbine.
  • the spring devices are arranged on different sides of a plane.
  • the plane runs parallel to the axis of rotation of the input shaft of the wind turbine transmission.
  • the plane can contain the axis of rotation of the input shaft.
  • the plane is aligned orthogonally to the support axis.
  • the directions of the forces with which the spring devices are loaded depend on the axis of rotation of the input shaft.
  • the direction of a drive torque, which is supported in the spring devices, and the direction of a weight force of the wind power transmission, which is introduced into the nacelle via the spring devices depend on the course of the axis of rotation.
  • one spring device is essentially loaded in compression and the other is essentially loaded in tension.
  • the spring device By choosing and designing the spring device, an improved adaptation to the forces to be supported is therefore possible.
  • the behavior of the arrangement can be optimized with regard to vibration loads.
  • the first spring device and/or the second spring device are rotationally symmetrical or rotationally symmetrical with respect to the support axis.
  • the first spring device and/or the second spring device have a shape that can be mapped onto itself by rotating through at least one angle about the support axis.
  • the first spring device and/or the second spring device can be rotationally symmetrical in the narrower sense.
  • the shape of the first spring device and/or the second spring device can be mapped onto itself by rotating it through any angle about the support axis.
  • the first spring device and the second spring device are developed to be mirror-symmetrical to one another with respect to the above-mentioned plane.
  • This allows the first spring device and the second spring device to be exchanged for one another.
  • the variety of components decreases, which leads to cost savings.
  • the first spring device is fixed in a first part of the means fixed to the housing.
  • the second spring device is fixed in a second part of the means fixed to the housing.
  • the mirror-symmetrical development requires that the first part and the second part of the means fixed to the housing are also mirror-symmetrical to one another with respect to the above-mentioned plane.
  • the above-mentioned plane intersects the means fixed to the housing and/or the means fixed to the nacelle. If the plane intersects the means fixed to the housing, the arrangement is constructed with spring devices which are arranged on different sides of the means fixed to the housing. Conversely, a structure results with spring devices which are arranged on different sides of the nacelle-fixed means when the plane intersects the nacelle-fixed means.
  • an arrangement of a part of the nacelle-fixed means between the first spring device and the second spring device and between a first part and a second part of the housing-fixed means is preferred.
  • the first spring device is arranged between the first part of the means fixed to the housing and the part of the means fixed to the nacelle or clamped between the first part of the means fixed to the housing and the part of the means fixed to the nacelle.
  • the second spring device is arranged between the second part of the means fixed to the housing and the part of the means fixed to the nacelle or clamped between the second part of the means fixed to the housing and the part of the means fixed to the nacelle.
  • the arrangement can be further developed in such a way that a part of the means fixed to the housing is arranged between the spring devices and between a first part and a second part of the means fixed to the nacelle, the first spring device being arranged between the first part of the means fixed to the nacelle and the part of the means fixed to the housing or is braced, and wherein the second spring device is arranged or braced between the second part of the nacelle-fixed means and the part of the housing-fixed means.
  • the nacelle-fixed means is at least partially arranged between the spring devices and a first part and a second part of the housing-fixed means. This results in mutatis mutandis, i.e.
  • the housing-fixed means is preferably further developed with a connecting element.
  • the connecting element therefore runs between the first part and the second part and merges into the first part or the second part at the respective connection point.
  • the transition can be designed in one piece.
  • the connecting element is connected in one piece to the first part and the second part of the means fixed to the housing.
  • the connecting element is, for example, cylindrical. In particular, it can have the shape of a straight circular cylinder.
  • the nacelle-fixed means has a recess. This is designed as a continuous hole through which the connecting element runs. Accordingly, the recess encloses the connecting element. Since the connecting element connects the first part and the second part of the means fixed to the housing, they are located on different sides of the recess.
  • the arrangement is preferably further developed with a third spring device. This serves to support the means fixed to the housing against the means fixed to the nacelle orthogonally to the support axis.
  • the third spring device is at least partially arranged in the recess of the nacelle-fixed means.
  • the third spring device in turn has a recess which is designed as a continuous hole through which the connecting element runs.
  • the development with a third spring device is advantageous because the third spring device can be designed independently of the first spring device and the second spring device. This makes it possible to support the means fixed to the housing against the means fixed to the nacelle in the orthogonal direction with a specifically adapted spring element, while the properties of the original support by the first spring device and the second spring device remain unchanged.
  • the first spring device and/or the second spring device are each developed in the form of a hollow truncated cone.
  • a hollow truncated cone is a truncated cone with a cavity.
  • the cavity also has the shape of a truncated cone.
  • the first spring device and/or the second spring device can support the means fixed to the housing both axially and radially against the means fixed to the nacelle. This eliminates the need for a third spring device.
  • the first spring device and second spring device which are further developed in the shape of a hollow truncated cone, are preferably directed towards one another with their tapered ends.
  • the first spring device and the second spring device have the shape of a hollow truncated cone, which tapers in the direction of the other spring device.
  • the hollow truncated cone, which describes the shape of the first spring device therefore tapers in the direction of the second spring device.
  • the hollow truncated cone which describes the shape of the second spring device, tapers in the direction of the first spring device. This results in a positive fixation of the nacelle-fixed means between the spring devices.
  • the nacelle-fixed means comprises a first part and a second part.
  • the first part and the second part form physically separate the separate pieces are not connected to one another in one piece.
  • the first part and the second part are joined together, preferably detachable.
  • the first spring device supports the means fixed to the housing against the first part. Accordingly, the second spring device supports the means fixed to the housing against the second part. In particular, the first spring device can support the first part of the means fixed to the housing against the first part of the means fixed to the nacelle, wherein the second spring device supports the second part of the means fixed to the housing against the second part of the means fixed to the nacelle.
  • the arrangement can be easily assembled and, in the case of a detachable joint connection, also dismantled.
  • a wind turbine according to the invention has a gearbox and a nacelle. According to the invention, the wind turbine also has three or four arrangements of the type described above, with which a housing of the gearbox is fixed in the nacelle.
  • the wind power system is preferably developed in such a way that the first spring device and the second spring device of the three or four arrangements are each arranged on different sides of the same plane that runs parallel to the axis of rotation of the input shaft of the transmission.
